HARNESS FOR LOOMS.

Application filed July 10, 1925. Serial No. 42,750.

The present invention relates to an improvement in harnesses for looms.

Harness frames, as ordinarily constructed, comprise top and bottom shafts and iron bars between to which the shafts are secured to form the harness frame. Ordinarily the iron bars are secured to the wooden shafts by means of screws. The shafts are made of thin pieces of wood and care is required to be exercised in driving the screws home in order to prevent splitting the shafts, there being necessarily required a preliminary formation of the hole to receive the screw and a tedious operation of driving the screws. According to the present invention the harness is formed of wooden shafts and iron bars, the connections between the shafts and bars being made by means of bolts, the object being to reduce the cost of manufacture, to improve the product and render it more durable. To these ends the invention consists in the loom harness hereinafter described and particularly defined in the claim.

In the accompanying drawing illustrating the invention Fig. 1 is an elevation of a loom harness frame constructed according to the present invention; Fig. 2 is a detail of one of the corners of the frame; and Figs. 3 and 4 illustrate modified forms of corner construction. The illustrated embodiments of the invention are described as follows: The harness frame has .a top shaft 1 and a bottom shaft 2. The bars 3, one on each end of the harness, serve to unite the two shafts. Each bar is bent at 4 at right angles to itself and is received in a rabbet 1n the end of the shaft. Each bar is also pro vided with two angle irons 5, the short legs of which are riveted to the bars 3 and the long legs of which are received in a second rabbet cut in the edges of the shafts. The leg 5 and the angle portion 4 of the bar embrace between them the end of the shaft and the latter is secured to these portions' i and 5 by means of a bolt 6 which has a short leg 7 and a long leg 8. The shaft is provided with two holes, one to receive the leg 8 and the other to receive the leg 7 on the bolt. Corresponding holes are required in the angle portions ti: and 5 of the bars. This bolt is inserted in the holes and wlnie the parts are held under pressure the end of the bolt is headed at 9, thereby securely uniting the shaft to the end bar. I

In the construction shown in Figure 8,

the bracket angle bar .10 is short and receives the long portion 12 of the bolt 11, the short leg l3 of the bolt being received in a hole on the right hand side instead of on the left as in the former construction. The parts are assembled as before and while clamped in position with respect to each other, the head 14 is riveted on the end of the long leg 12 of the bolt. This forms a strong connection between the shaft and the end bar which is easily and readily assembled and durable in use.

In Figure 4.- a second modification is shown in which the bolt 15 is shown as provided with two long legs 16 and 17, both extending entirely through the shaft 1 and having both of its ends 16 and 17 riveted at 18 and 19.

The forms of harness shown are readily manufactured, the shafts being prepared in the usual wood working machinery to exact sizes, the iron bars and brackets being drilled to receive the bolts and then they are quite readily assembled by simple assembling processes-while two brackets are held clamped upon the end of a shaft the bolts are secured in place by riveting'or in any other suitable manner. The use of a double shank bolt contributes to the strength of the harness. The use of these bolt holes in the shaft facilitates assembly.

Having thus described the invention, what is claimed is:

A harness frame for looms comprising shafts and end bars, the end bars being united to the ends of the shafts by being provided with a right angle portion and an angle bar secured to the end bar so that its angle arm projects longitudinally of the shaft, the end of which is'received between the right angle portion of the end bar and the arm of'the angle bar, the end of the shaft being provided with two bolt holes, the right angle portion of the end bar having two bolt holes registering therewith and the arm having a bolt hole registering with one of such holes and a double-shank bolt having a portion connecting the shanks, one shank passing through the registering 110165 of the right angle portion, arm and shaft: and the second shank passing through the second hole in the right sum-1e nortion and entering the second hole in the shaft, the connecting portion of the bolt engaging the surface of the right angle portion of the end bar.

In Leetimony whereoi I have signed my name to this specification.
